Model-Based Compressive Sensing for Multi-Party Distant Speech Recognition

Hervé Bourlard, Volkan Cevher, Afsaneh Asaei

We leverage the recent algorithmic advances in compressive sensing, and propose a novel source separation algorithm for efficient recovery of convolutive speech mixtures in spectro-temporal domain. Compared to the common sparse component analysis technique ...

TGR5 Activation Inhibits Atherosclerosis by Reducing Macrophage Inflammation and Lipid Loading

Johan Auwerx, Kristina Schoonjans, Mitsunori Nomura, Thijs Pols, Taoufiq Harach, Maaike Hélène Oosterveer, Giuseppe Lo Sasso

The G protein-coupled receptor TGR5 has been identified as an important component of the bile acid signaling network, and its activation has been linked to enhanced energy expenditure and improved glycemic control. Here, we demonstrate that activation of T ...

Flexible and Robust Calibration of the Yule-Nielsen Model for CMYK Prints

Thomas Bugnon

Spectral reflection prediction models, although effective, are impractical for certain industrial applications such as self-calibrating devices and online monitoring because of the requirements imposed by their calibration. The idea emerged to make the cal ...

Experimental investigations on welded double lap joints composed of timber

Yves Weinand, Till Vallée, Bernhard Stamm, Benjamin Hahn

Fabrication of wood-to-wood connections by means of friction welding is an relatively new process holding high potential for development. To connect wooden pieces by means of friction welding, they are initially pressed against each other. The rapid moveme ...

Spatio-temporal filtering for EEG error related potentials.

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Inaki Asier Iturrate Gil

This paper presents a new filter for EEG Event-Related Potentials that relies on spatio-temporal features. The results are analyzed with error-related potentials, and compared to the results obtained with Independent Component Analysis. Additionally, the o ...

Prediction and validation of sidesway collapse of two scale models of a 4-story steel moment frame

Dimitrios Lignos

A research program is summarized in which collapse of a steel frame structure is predicted numerically and the accuracy of prediction is validated experimentally through earthquake simulator tests of two 1:8 scale models of a 4-story code-compliant prototy ...

Steerable Pyramids and Tight Wavelet Frames in L_2(R^d)

Michaël Unser, Dimitri Nestor Alice Van De Ville

We present a functional framework for the design of tight steerable wavelet frames in any number of dimensions. The 2-D version of the method can be viewed as a generalization of Simoncelli's steerable pyramid that gives access to a larger palette of steer ...

Activelets: Wavelets for sparse representation of hemodynamic responses

Michaël Unser, Dimitri Nestor Alice Van De Ville, Ildar Khalidov, François Lazeyras

We propose a new framework to extract the activity-related component in the BOLD functional magnetic resonance imaging (fMRI) signal. As opposed to traditional fMRI signal analysis techniques, we do not impose any prior knowledge of the event timing. Inste ...

On the hazard rate and reversed hazard rate orderings in two-component series systems with active redundancies

The lifetimes of two-component series systems with two active redundancies are compared using the hazard rate and the reversed hazard rate orders. We study the problem of where to allocate the spares in a system to obtain the best configuration. We compare ...
